Abstract
Systems and methods disclosed herein are directed towards the fabrication of a nanomesh composite filter (NCF) that can be manufactured according to various embodiments, all of which are intended to be fabricated in order to control the transmission, reflection, and absorption of various wavelengths bands. In particular, the disclosed embodiments may be used for heat shielding applications where certain wavelength ranges may be desirable to transmit and others may be desirable to reflect.
